When a Cisco router is being moved from an IPv4 network to a complete IPv6 environment which series of commands would correctly enable IPv6 forwarding and interface addressing?

To enable IPv6 forwarding and configure interface addressing on a Cisco router moving to an IPv6 environment, you would first enter global configuration mode and enable IPv6 routing with the command ipv6 unicast-routing. Next, you would access the specific interface using interface <interface-name> and assign an IPv6 address with the command ipv6 address <ipv6-address>/<prefix-length>. Finally, use the command no shutdown to activate the interface.
